Shoulder force measurements using an artificial joint

本研究的最初目的是开发一种仪器传感器，尸体试验，测量手术期间的肩关节力，并使用肌肉骨骼计算机模型进行理论计算。除了计算机模拟之外，我们已经完成了所有的目的。我们已经开发了能够在RTSA操作期间测量肩部力的传感器。我们在两具尸体上进行了尸体试验，并在佛罗里达大学使用我们开发的传感器对26名患者进行了肩力测量。外展结束时测得平均195牛的力值。

The original purposes of this study were to develop an instrumented sensor, cadaver trial experiments, to measure shoulder joint forces during operation, and theoretical calculation using a musculoskeletal computer model. We have completed the every purpose except the computer simulation. We have developed the sensors capable of measureing shoulder forces during RTSA operation. Cadaver trials were performed on two cadavers and shoulder force measurements on 26 patients were completed at the University of Florida using the sensor that we have developed. Mean force value of 195 N were observed at the terminal of abduction.
